MIXING APPARATUS.

SPECIFICATION forming part of Letters Patent N o. 673,196, dated April30, 1901. Application filed July 12, 1900. Serial No. 23,351. (Nomodel.)

To a/ZZ whom, it may concern:

Be it known that I, JOHN B. CLINE, of Jefferson, county of Greene, andState of Iowa, have invented a new and useful Improvement in MixingApparatus, of which the following is a specification.

The object of this invention is to prod uoe a device by means of whichvarious subst-ances in finely-divided, pulverized, or granular form maybe rapidly, thorough-ly, and intimately mixed; and to this end theinvention consists of a casing or vessel of peculiar form to receive theingredients to be mixed and adapted for rotation, as will be more fullydescribed hereinafter.

The device is designed more particularly for mixing drugs in the form ofpowders and the like; but it is applicable as well for mixing plasters,food, and `analogous substances where the conditions require a thoroughintermingling of different ingredients.

In the accompanying drawings, Figure 1 is a side elevation of my device.Fig. 2 is afront elevation of the same. Eig. 3 is a verticallongitudinal sectional elevation on'the line a a. of Fig. 4, showing theposition of the mass within the vessel when the latter is in operation.Fig. 4 is a vertical transverse sectional elevation on the line b o ofFig. 1.

Referring to the drawings, my device comprises a hollow vessel or casing1 of the general form of two cones placed base to base, the sides 2 and3 of the casing having a sharp slope or inclination from the centralwidest portion to the ends 32L and 4, so there will be tendency of thecontents to gravitate toward the center. This casing is mounted in anappropriate manner to revolve on an axis extending centrally andhorizontally through the same from end to end, and for this purpose itis provided at its ends with horizontal outwardly-extending spindles and6, mounted to revolve in bearings 7 and 8, one of the spindles beingprovided with a driving-pulley 9, adapted to be driven from a suitablesource of power, or the spindle may be provided with a crank 10, asindicated by dotted lines in Fig. 2, to be turned by hand.

The interior sloping sides of the casing are made upof a series of fiatsmooth adjoining surfaces 11 12 13, &c., each of a different angle fromthe adjacent surface, and these surfaces are widest at the center of thecasing, froln which point they converge gradually to the ends, wherethey join vertical parallel Walls constituting, respectively, the endsof the casing. l

The substances to be mixed are introduced into the casing through'anopening near the center closed by a door 15, hinged, as at 16, to theside and provided with a spring-finger 17, adapted when the door isclosed to engage over a flange 18, projecting from the center of thecasing.

In the operation of the device the casing is rotated in the direction ofthe arrow in Fig. 3 at such a speed as to maintain the mass in suchposition that its surface will extend at or about an angle of forty-fivedegrees, as represented in Fig. 3. The continued rotation of the casingwill tend to lift the mass, the outer portions by reason of the slopingsides gravitating toward the center, as clearly indicated by arrows inFig. 4, where they will displace the central portion of the mass,forcing the particles outward to the sides, whence they will return, asbefore, to the center. It is seen, therefore, that there is a generalmovement of the particles of the mass from the center outward inopposite directions and -their return to the center of the casing. As aresult of this action and the continually-changing angles of the surfaceof the casing supporting the mass the different ingredients arethoroughly mixed, each particle meeting every other particle, and -theirintimate mingling effected in a rapid and eective manner.

Having thus described my invention, what I claim is- 1. A mixingapparatus comprising a hollow casing having its sides sloping sharplytoward its ends and of general conical form and mounted to revolve on ahorizontal axis passing through the ends, said casing having theinterior of its sides formed of a series of iiat adjoining surfaces eachof a different angle from the adjacent surface.

2. A mixing apparatus comprising a hollow casing having its sidessloping sharply toward its ends and of general conical form and mountedto revolve on a horizontal axis pass- IOO ing through the ends, saidcasing havingthe hand this 25th day of June, 1900, in the presinteriorofits sid'es formed of a series of dat ence of two attesting Witnesses.

adjoiniuo surfaces each of a different anule from thebadjacent 7surfaceand said surfaes JN0' B' CLINE 5 converging from the center of Jsheeasing Witnesses:

gradually toward its ends. H. V. CLINE,
